Review: It works! - Needed to connect a solar inverter to hardwire to the net, so I could use home assistant. Works well, if it stops then restart your vm ( device running home assistant ) . Has been stable for couple of months now
Review: Perfect for the job required - I needed to connect my Solax PV inverter to Home Assistant, & wanted it wired rather than wireless. This did the job admirably for a reasonable price & has a good GUI.

### ⭐⭐⭐⭐⭐ Perfect for the job required
*by A***R on 18 November 2023*

### ⭐⭐⭐⭐ Review
*by B***7 on 1 January 2025*

Nachdem Proxmox beim Durchreichen von USB Devices zickt, wollte ich das Problem mittels Hardware lösen. Dafür taugt der Konverter auch wirklich gut. Einen Punkt Abzug gibt's dafür, dass das Gerät nicht standardmäßig auf DHCP konfiguriert ist, sondern dies über eine eigene Software umgestellt werden muss, die man erst nach ein wenig Suchen im Wiki des Herstellers findet. Wirklich vermeidbar wäre es auch gewesen, dass das Gehäuse um ca. 1mm zu hoch ist im Bereich, wo die Blende die Hutschienengeräte durchragen lässt... hier muss ich wohl noch die Blende ausschneiden, damit das wirklich passt.
